GAS BURNER.

Application filed March 10. 1927.

My invention relates to gas burners and particularly to those suitable for employment with burner tubes or radiants.

()ne object of nrv invention is to provide a burner having burner heads or oritiees so arranged that there is a better mixture and combustion of gas and air.

Another objeet of my invent on is to piovide a burner having means for preventing the radiation oi heat. vertieallv downward to the ttoor.

further objeet of my invention s to pi oviilo an improved torm. ol' eonneetion hetween a mixing valve and a burner.

Still another objeet of my invention is to simplitv and improve generally the strutture and operation ot gas burners.

One form whiea nrv invention may take is shown in the aerompaliv ng drawing. wh rein Figure l is a plan v ew ot' a burner and radiant support; Fig. 2 is a side elevational view ot the same; Fig. I) is a s-eetional view taken on the line ill-111 oi Fig. 2. and Fig. 4 is a seetional \"ew taken on the line TYIV of Fig. L.

In the drawing. T have shown a burner having a body portion an inlet (3. azrl a series ot burner heads or oritit-e members 7.

The burner is supplied from a gas line 8 past a main eontrol valve 9 and a ne dle valve It). the needle valve being operated by a thumb srrew ll. in somewhat the tlt'itztl manner.

braehet 1: 2 is -aipported by and has serew-thr aded adjustment with respeet to the valve it). bolt 13 that extends through a boss ii of the burner serves to eonneet the parts 12 and it together and permit adjustment oi the burner 5 relative to the needle valve in a longitudina direetiion. A disk has threaded eonneetion with the valve. it) and is rotatable to eti' et adjustment thereof longitudinall ot the valve. so as to permit the proper amount of air to enter the intake end t} (it the burner.

The burner 53 is provided with attaching lug, 17 by means of which it may he mounte'l upon a stove frame. in the manner shown in the Sharpe Patent #1546945. for example. Since the frame or body portion of the stove eonstitutes no portion of the present invention, a detailed description thereof is unnecessary. The burner 5 is provided with wing portioi s 18 and 19 that prevent Serial No. 174150.

relleetion of heat downwardlv to points he neath the stove. i

A burner plate 20 is seeured to the burner 5 by means of attaching lugs 21 and Ferews 22. and supports burner tithe or radiants 23 being provided with upturned tongues 21 and a rib 25 that form g ooves to support the front lower edges of the tubes. The tubes are supported against rearward tilting movement. by lugs or stops 26. that are tormed on a hark wail 26 that. mav be mounte-i in the t'ranieworl: ot' the stove (not shown) in the manner shown in the said pateut.

The burner heads '4' are eaeh provided with six holes or oritiees tor the passage of gas. a groove '1 being 'lormed in raeh oi the head so that air may ieadilv enter between the streams ot gas flowing from eaeh burner h ad. and there being three streams ot' gas at eaeh side ot the respeetive grooves T. l boss 27 is provided adjaeent to eaeh end ot the burner. in order to serve as an abutment for one ot the fastening lugs 21 ot the burner plate. l

T)) V reference to Fig. 3. it will be seen that the lower ends of the. tub s 23 are suit-stautially unobstrueted and that the rear lower walls thereof are disposed in spaeed relat on to the lower edge of the tire hael; 26. to that air t'or seeondarv eomhustion niav flow rip-- wardlv hetweei'i he adiarent wal s oi. the

From the t'oregoing it will lie seen that i provide a stru -lure where n it is possibie to tpzieltlv and aeeurate v eonneet the burner to k line. bv reason ot' the relativelv adiustahle hraehets iii and H earried bv the s valve and the hurn r respeetivelvi that waste through relieetion of heat to points benetth the stove is avoided hv reason ot the shields l8 and 19: that tlli t'lilt'lfilit air .iture obtained through provision of grooves T and elevation of the burner tubes 2?; above the burner heads. with their lower ends substantially u obstructed, and the tubes are t- 'upport d at. their lower ends against displaeement in horiyut ntal d reetions. by the null tongues 2 whieh. bv reason of the flared lower end of the tithe, do not materially interfere with the flow of air into the. tube.

I elaim as my invention Burner structure comprising a burner headhavin a plurality of orifices disposed lon itudi ah thereof, a fi're ters stipport disposed above ahd to the front of the said orifices, a series of tongues extending from the rear edge of said support, each adapted to engage the Tower eclge of a burner tube to support the same, and each being of small Width relative to the internal diametehs of the tubes, and a tubesupp0rting member jelispbs'eil above and to the r'eoT'r of the burner 10 head, for preventing i'arsvzti'd tilting of fire tribe's.

In testimony whereof I, the said WILLIAM L. SHARP have hereunto set my hand.
